mine started off with a roar from cold but now roars intermittently but constantly thru the gears,can cause this to happen by changing down hard.Believe me this is not something you would want to hear all the time.
Landrover have said that this is caused by the injector pump which has been replaced but no improvement found.

The viscous fan unit is electronically controlled by the
ECM to optimise fan speed for all operating conditions.
NOTE: If the electrical connections to the viscous fan
are disconnected the fan will 'idle' and overheating may
result. The ECM stores the appropriate fault codes in
this case.
